JP 2009-230640 A

  Some recent display operation devices employ a touch pad or a touch panel that can be slid on the operation surface with a finger. However, in this case, the user who performed the slide operation cannot determine whether the user wants to switch the selection to the destination candidate located in the slide direction or to scroll the map in the slide direction.

  In particular, when a plurality of destination candidates are crowded, it is difficult to select a desired destination candidate by a tap operation (an operation of tapping the operation surface with a finger). It is necessary to switch the selection of destination candidates by a slide operation. However, even if the slide operation is performed with such an intention, if the map scrolls against the intention, the selection of the destination candidate cannot be switched.

  In addition, the said subject is not restricted to displaying a some destination candidate on a map. For example, when multiple button icons (selection candidate points) are displayed on the page layer (background), you want to switch the selection to a button icon located in the slide direction, or want to scroll the page layer in the slide direction The display operation device cannot determine whether or not.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a display operation device that avoids an unintentional display.

  The first invention for achieving the above object is characterized by the following points. That is, the display operation device includes a touch operation unit (14) operated with a finger on the operation surface, and changes the display content of the display (20) according to the operation of the touch operation unit. The display content of the first layer and the display content of the second layer are displayed in an overlapping manner, and the display of the second layer is performed without changing the display content of the first layer according to the operation of the touch operation means. Mode switching operation means (14a, 19) for switching between a first operation mode for changing contents and a second operation mode for changing display contents of the first layer according to the operation of the touch operation means. It is characterized by providing.

  According to this, the user can switch between the first operation mode and the second operation mode by operating the mode switching operation means prior to the slide operation. Therefore, the display operation device can determine whether the user who has operated the touch operation means wants to change the display content of the first layer or the display content of the second layer. Therefore, it can avoid that it becomes a display contrary to a user's intention.

  Furthermore, in the second invention, the touch operation means (14) capable of sliding operation on the operation surface with a finger is provided, and the background display (M, L) of the display (20) is scrolled without scrolling the background. A selection mode in which a selection candidate point at a position corresponding to the slide operation among a plurality of selection candidate points (21 to 23, 24 to 28) displayed on the display is displayed in a manner different from other selection candidate points. And a mode switching operation means (14a, 19) for switching between a first operation mode and a scroll mode (second operation mode) for scrolling the background display in accordance with the slide operation. .

  According to this, the user operates the mode switching operation means prior to the slide operation to select the selection candidate point at the position corresponding to the slide operation while prohibiting the scrolling of the background display, and the slide operation. The scroll mode in which the background display is scrolled can be switched according to the above. Therefore, the display operation device can determine whether the user who performed the slide operation wants to scroll the background in the slide direction or to switch the selection to a selection candidate point located in the slide direction. Therefore, it can avoid that it becomes a display contrary to a user's intention.

  Hereinafter, each embodiment showing a display operation device according to the present invention will be described with reference to the drawings. In the following embodiments, parts that are the same or equivalent to each other are denoted by the same reference numerals in the drawings, and the description of the same reference numerals is used.

(First embodiment)
As shown in FIG. 1, the display operation device 10 is mounted within a range of a vehicle driver (user) within the vehicle interior. The content of the operation by the display operation device 10 is displayed on the remote display 20 (display). The distant display 20 is installed in the vicinity of the front windshield 30. The display operation device 10 is installed on the design panel 31 (installation member) of the center console located between the driver seat and the passenger seat. That is, the display operation device 10 and the remote display device 20 are disposed separately from each other, and the remote display device 20 is disposed above the display operation device 10.

  Thus, by disposing the display operation device 10 and the distant display unit 20 separately, the driver can view the distant display unit 20 without greatly moving the line of sight when driving the vehicle. In addition, since the display operation device 10 can be disposed near the driver, the driver can operate the display operation device 10 while maintaining the posture during traveling.

  The display operation device 10 is a device that operates the operation content of a plurality of devices (operation target devices) mounted on the vehicle by operating the display content of the remote indicator 20. Specific examples include navigation devices, audio devices, televisions, radios, air-conditioning devices and the like mounted on vehicles (see reference numeral 40 in FIG. 2). The remote display 20 displays the operation contents for the various devices 40 described above, and also displays operation states of the various devices 40 and operation menus determined by operations of the display operation device 10. In the example of FIGS. 3 and 4, the map M or the like by the navigation device is displayed on the remote display 20.

  The display operation device 10 includes a plurality of operation switches 11, 12, 13 and a touch pad 14 (touch operation means) that are manually operated by a user. The operation switches 11 to 13 are mechanical switches for manually turning on / off the contact state of the terminals, and a plurality of the operation switches 11 to 13 are arranged in the vehicle left-right direction (left-right direction in FIG. 1). These operation switches 11 to 13 are assumed to be operated by the ring finger, middle finger, and index finger of the driver's left hand, respectively.

  The touch pad 14 is configured by a known capacitance type. The touch pad 14 is disposed adjacent to the operation switches 11 to 13, and is disposed below the operation switches 11 to 13 or on the vehicle rear side in the example of FIG. 1. The touch pad 14 detects the movement of the driver's fingertip on the operation plate based on a change in capacitance. Specifically, the fingertip contact position on the operation plate, the fingertip trajectory when the operation plate is traced with the fingertip, the operation of tapping the operation plate with the fingertip (tap operation), the fingertip touching the operation plate to the target position A tracing operation (sliding operation), an operation of quickly touching the fingertip touching the operation plate (flick operation), and the like are detected. Note that the tap operation may be detected by mounting a pressure sensor that detects a fingertip pressing force on the operation plate on the touch pad 14 or may be detected based on a change in capacitance.

  These operation switches 11 to 13 and the touch pad 14 can be blind-operated. That is, the driver can operate each device 40 by blindly operating the display operation device 10 while looking at the map M and the operation menu displayed on the distant display 20.

  As shown in FIG. 2, the display / operation device 10 includes an electrostatic detection circuit 16, an MPU 17 (micro processing unit), and a communication circuit 18 in addition to the operation switches 11 to 13 and the touch pad 14. The touch pad 14 outputs a capacitance change caused by the fingertip operation to the electrostatic detection circuit 16 as a fingertip operation signal. The electrostatic detection circuit 16 outputs a fingertip operation signal to the MPU 17 as a serial signal.

  The MPU 17 generates and outputs an operation signal based on the fingertip operation signal output from the electrostatic detection circuit 16 and the on / off signals output from the operation switches 11 to 13. The communication circuit 18 performs bi-directional communication between the remote display 20 and various devices 40 and the MPU 17 using a communication protocol such as CAN. As a result, the operation signal output from the MPU 17 can be transmitted to the remote display 20 and various devices 40. The remote display 20 and the various devices 40 operate with the control content according to the operation signal.

  FIG. 3 and FIG. 4 show one mode when the map M (background) by the navigation device 40 is displayed (background display) on the distant display 20, and the user is interested in the map M. A plurality of POIs 21, 22, and 23 (Points Of Interest) that are points to be held are displayed. Specific examples of the POIs 21 to 23 include vehicle destination candidates (selection candidate points). In addition, the 1st layer which displays the map M, and the 2nd layer which displays POI21-23 are comprised by a separate layer, By superimposing and displaying these both layers, FIG. 3 and FIG. 4 is displayed. A pointer P is displayed on the map M. When an operation of sliding the fingertip in an appropriate direction with the fingertip in contact with the surface of the touch pad 14 (hereinafter referred to as “sliding operation”), the display position of the pointer P according to the sliding amount and the sliding direction is performed. Move. The POI on which the pointer P is located among the plurality of POIs 21 to 23 is highlighted in a manner different from other POIs. In the example of FIG. 3A, the POI 21 is surrounded by a double line 21k, and in the examples of FIGS. 3B and 4, the POI 22 is surrounded by a double line 22k to be highlighted.

  As described above, when it is desired to change the selected POI 21 to another POI 22, the position of the pointer P may be moved by a slide operation. However, if the map M scrolls with this slide operation, it becomes difficult to position the pointer P on the desired POI 22. Therefore, in the present embodiment, a selection mode (first operation mode) in which the pointer P can be moved by a slide operation while prohibiting scrolling of the map M, and a scroll mode in which the map M is scrolled in accordance with the slide operation (first operation). 2 operation mode).

  For example, in the selection mode, if the slide operation is performed to move the pointer P toward the POI 22 in a state where the POI 21 is selected and highlighted as shown in FIG. In this state, the pointer P moves and the selected POI can be switched to the desired POI 22 as shown in FIG.

  Further, in the scroll mode, when the slide operation is performed so that the pointer P is moved from the position of FIG. 4A to the position of FIG. 4B, the map M is displayed according to the slide amount and the slide direction for the slide operation. Scroll.

  This mode switching is performed by mode switching operation means described below. That is, as indicated by a one-dot chain line 14a in FIG. 5, a part of the operation surface of the touch pad 14 is assigned as the mode switching operation unit 14a, and the mode switching operation unit 14a functions as a mode switching operation unit. In the example of FIG. 5, it is assumed that the vehicle driver touches the mode switching operation unit 14 a with the thumb of the hand on the passenger seat side, and the driver side (the right side in FIG. 1) of the operation surface of the touchpad 14. Is set as the mode switching operation unit 14a.

  The touch pad 14 can detect two fingers simultaneously. Specifically, both the first finger that touches the mode switching operation unit 14a and the second finger that slides a portion other than the mode switching operation unit (normal operation unit 14b) can be detected simultaneously. It is configured.

  When the mode switching operation unit 14a is touched, the mode is switched to the selection mode, and when the finger is released from the mode switching operation unit 14a, the mode is switched to the scroll mode. Therefore, when the normal operation unit 14b is slid without touching the mode switching operation unit 14a, the pointer P moves while the map M scrolls in the scroll mode. On the other hand, when the normal operation unit 14b is slid with the second finger (finger other than the thumb) while the mode switching operation unit 14a is touched with the first finger (for example, the thumb), the pointer of the map M is prohibited from being scrolled. P moves.

  In the example of FIG. 4, even in the scroll mode, the POI selection can be changed in the same manner as in the selection mode. For example, when the pointer P is tapped on the desired POI 22 in the scroll mode, the highlighted display is changed on the POI 22 and the selection is changed.

  As shown in FIGS. 3 and 4, the display 20 is provided with a selection mode display unit 20a. In the selection mode, the selection mode display unit 20a is displayed in a different mode from that in the scroll mode. It is comprised so that a user may visually recognize whether it is. The mode display unit 20a may be a color display or a character display such as a message. In FIG. 3, by displaying the mode display unit 20a, it is possible to allow the user to recognize that only the pointer P moves while the scrolling of the map M is prohibited.

  Although not shown in FIGS. 3 and 4, in the selected state in which the pointer P is positioned on the POI and highlighted, the selected POI 23 (destination) is displayed as indicated by reference numeral 20b in FIG. Information on candidates (for example, destination information) is displayed in a pop-up. The pop-up display 20b is displayed at a position that does not overlap the pointer P when the POI selection is changed. That is, in the example of FIG. 6, since the pointer P is an upward arrow, the pop-up display 20b is positioned above the pointer P so that the pop-up display 20b does not overlap the pointer P.

  When the pointer P is placed on the desired POI or the pop-up display of the POI, and the combined state is continued for a predetermined time or longer, the selection of the POI is determined and the command assigned to the pop-up display of the POI or the POI Is executed. For example, detailed information on the destination is displayed.

  When the pointer P is moved to change the selection of the POI, if both the pop-up display 20b and the POI are displayed overlapping at the position selected by the pointer P, the selection has priority over the selection of the pop-up display 20b. The POI selection is executed to change the POI selection.

  Next, a control procedure for switching the scroll mode and the selection mode will be described with reference to FIG. Note that the processing of FIG. 7 is repeatedly executed by the MPU 17 at a predetermined cycle.

  First, in step S10 of FIG. 7, it is determined whether or not the mode switching operation unit 14a is touched. When it is determined that there is no touch (S10: NO), the display content of the remote display 20 is controlled in the scroll mode in the subsequent step S20. If it is determined that the touch is present (S10: YES), the display content of the remote indicator 20 is controlled in the selection mode in the subsequent step S30.

  In the subsequent step S40, it is determined whether or not the same POI or pop-up display is selected for a predetermined time or more. If the determination is affirmative (S40: YES), the command of the POI selected in the subsequent step S50 is determined. Execute. That is, detailed information regarding the selected POI is displayed.

  As described above, according to the present embodiment, the following effects are exhibited.

  Prior to the slide operation, the user operates the mode switching operation unit 14a to switch between a scroll mode in which the map M is scrolled and a selection mode in which the POI selection can be changed while prohibiting the map M from being scrolled. be able to. Therefore, the MPU 17 can determine whether or not it is desired to prohibit the scrolling of the map M, so that it is possible to avoid scrolling the map M against the user's intention.

  Since a part of the operation surface of the touch pad 14 is assigned as the mode switching operation unit 14a, the mode switching operation can be realized with a small number of parts compared to a case where a switch dedicated to mode switching is newly provided.

  The touch pad 14 is configured to be able to simultaneously detect both the first finger that touches the mode switching operation unit 14a and the second finger that slides the normal operation unit 14b. Therefore, since the operation for switching to the selection mode and the slide operation can be simultaneously performed with one hand, the operability can be improved.

  When the same POI is selected for a predetermined time or more by the slide operation, the selection of the POI is determined and the command assigned to the POI is executed, so that both the slide operation in the selection mode and the POI command execution operation are performed. Can be realized by operating the touch pad 14.

  The display operation device 10 and the remote display device 20 are configured to be able to communicate with each other, and the remote display device 20 is arranged in the passenger compartment near the line of sight when driving the vehicle, and displayed on the hand side when driving the vehicle. An operating device 10 is arranged. Therefore, the user can visually recognize the distant display device 20 while blindly operating the display operation device 10 in the state of driving the vehicle. In the case of such a separate configuration, it is difficult to move the pointer P to a desired position by tapping the touch pad 14, and it is realistic to move the pointer P by a slide operation. Therefore, in the display system in which the display operation device 10 and the remote display device 20 are separated, the above-described effects such as “it becomes possible to determine whether or not it is desired to prohibit the scrolling of the map M” are effectively exhibited.

(Second Embodiment)
In the present embodiment, switching to the selection mode is permitted on condition that the degree of congestion of a plurality of POIs is equal to or greater than a predetermined level. Specifically, in the process of FIG. 7 according to the first embodiment, the process of step S5 indicated by the alternate long and short dash line in FIG. 7 is added before step S10. In step S5, it is determined whether or not the POI density is greater than or equal to a predetermined value. If an affirmative determination is made (S5: YES), the process proceeds to step S10, and mode switching is executed according to the operation content of the mode switching operation unit 14a. On the other hand, if a negative determination is made (S5: NO), the process proceeds to step S20, and display control is performed in the scroll mode regardless of whether or not the mode switching operation unit 14a is touched.

  Here, if the POI density is low, it is often not difficult to select a desired POI by a slide operation even if the map M scrolls. Alternatively, it is often not difficult to select a desired POI by a tap operation. On the other hand, if the POI density is high, it is difficult to select a desired POI by a slide operation unless the scrolling of the map M is prohibited. Alternatively, it is difficult to select a desired POI by a tap operation.

  In view of these points, in the present embodiment, switching to the selection mode is permitted when the POI density is high, and switching to the selection mode is prohibited when the density is high. Therefore, scrolling of the map M can be prohibited only when necessary, which is preferable.

(Third embodiment)
In the first embodiment, the display operation device 10 and the display (distant display device 20) are separated from each other. However, in this embodiment, as shown in FIG. 8, the touch pad 14 (display operation device 10) is configured. And the display 15 are integrally formed.

  Specifically, the touch pad 14 is arranged on the display surface of the display 15, the surface functions as an operation surface of the touch pad 14, and the electrostatic force when the display surface of the display 15 is operated with a finger. The touch pad 14 detects the capacitance change and outputs it to the electrostatic detection circuit 16 as a fingertip operation signal. In short, the display 15 and the touch pad 14 function as a so-called touch panel device.

  In the present embodiment, the selection mode display unit 20a may function as the mode switching operation unit 14a. That is, when the selection mode display unit 20a is touched, the mode is switched to the selection mode, and when the finger is released from the selection mode display unit 20a, the mode is switched to the scroll mode. Accordingly, when another display unit is slid without touching the selection mode display unit 20a, the pointer P moves while the map M scrolls in the scroll mode. On the other hand, when the selection mode display unit 20a is touched with a first finger (for example, a thumb) and another display unit is slid with a second finger (a finger other than the thumb), scrolling of the map M is prohibited. P moves.

(Fourth embodiment)
In the first embodiment, whether to scroll the display of the map M (background) by the navigation device is switched. On the other hand, in this embodiment, as shown in FIGS. 9 and 10, whether to scroll the display of the song title selection layer L (background) by the audio device is switched. Note that the song title displays 24 to 28 in the figure are displayed on the song title selection layer L.

  Specifically, in the selection mode, when a slide operation is performed so as to move the pointer P toward the POI 26 in a state where the POI 24 is selected and highlighted as shown in FIG. As shown in FIG. 9B, the selected POI can be switched to the desired POI 26 by moving the pointer P in a state where the scrolling is prohibited.

  In the scroll mode, when the slide operation is performed so that the pointer P is moved from the position of FIG. 10A to the position of FIG. 10B, the song title selection layer L is scrolled according to the slide amount required for the slide operation. To do.

  As described above, the same effects as those of the first embodiment are also exhibited by this embodiment. In short, in the present invention, the scroll control target is not limited to the map M, and the song title selection layer L may be the scroll control target as in the present embodiment, for example.

(Other embodiments)
The present invention is not limited to the description of the above embodiment, and may be modified as follows. Moreover, you may make it combine the characteristic structure of each embodiment arbitrarily, respectively.

  -In the said 2nd Embodiment, this invention is applied to the touchscreen which comprised the touchpad 14 and the display 15 integrally, and this touchscreen is a fixed type mounted in the instrument panel etc. of a vehicle interior. On the other hand, a portable touch panel may be applied to the present invention, and the portable touch panel may be brought into the vehicle compartment and used.

  -In the said 1st Embodiment, the display operation apparatus 10 and the display 15 are comprised separately, and this display operation apparatus 10 is a fixed type mounted in the center console etc. of the vehicle interior. On the other hand, a portable display operation device may be applied to the present invention, and the portable display operation device may be brought into the passenger compartment and communicated with the display 15 for use. Alternatively, the portable display operation device can be used alone without communicating with the display 15.

  5 may be provided on the touch pad 14 instead of the mode switching operation unit 14a illustrated in FIG. In this case, it is assumed that the vehicle driver presses the changeover switch 19 with the thumb of the hand on the passenger seat side, and the driver switches to the driver side (right side in FIG. 1) among the side surfaces of the case housing the touchpad 14. It is desirable to arrange the switch 19. The mode switching operation can be realized by operating the changeover switch 19. The changeover switch 19 may be a mechanical type, an electrostatic type, or a resistance film type.

  -In the said 1st Embodiment, you may make it switch to selection mode on the condition that the mode switching operation part 14a was continuously touched more than predetermined time. According to this, when it touches the mode switching operation part 14a for a moment contrary to the intention, it can avoid switching to selection mode. Further, since it is not necessary to slide the normal operation unit 14b of the touch panel 14 with an index finger or the like while touching the mode switching operation unit 14a with the thumb, the operability is improved.

  In the first embodiment, the selection mode is executed only when the mode switching operation unit 14a is touched. However, after the mode switching operation unit 14a is touched to switch to the selection mode, the mode switching operation unit 14a is operated. Control may be performed so that the selection mode is maintained even when the finger is removed from the screen. In this case, what is necessary is just to control to switch to scroll mode by touching the mode switching operation part 14a again.

  In the first embodiment, in the selection mode, the moving amount of the pointer P is set in proportion to the sliding amount of the sliding operation, and the sliding direction is matched with the moving direction of the pointer P. As a modification, in the selection mode, the pointer P may be moved to a POI closest to the pointer position in the sliding amount and the sliding direction so that the pointer P is always positioned on any POI. .

  In the first embodiment, the POI is highlighted by surrounding the POIs 21 and 22 with the double lines 21k and 22k. However, the POI may be highlighted by changing the display color of the POI (for example, reverse display). Good.

  In the first embodiment, the display position of the pointer P is moved according to the slide operation, but the pointer P may be hidden.

  In the first embodiment, the POI selection change is permitted in the scroll mode, but the POI selection change may be prohibited in the scroll mode.

  In each of the above embodiments, when a slide operation is performed, the display method is changed between the selection mode (first operation mode) and the scroll mode (second operation mode), but operations other than the slide operation are performed. Even in this case, the display method may be changed between the first operation mode and the second operation mode. For example, when an operation (double-tap operation) in which the tap operation is continuously performed a plurality of times is performed, in the second operation mode, the map M is enlarged and displayed around the double-tapped position. On the other hand, in the first operation mode, information related to the POI at the double-tapped position is displayed.

  In each of the above embodiments, the display content of the first layer is described as background display, and the display content of the second layer is described as a plurality of selection candidate points. However, the display content of the first layer is described as a plurality of selection candidate points. The display content of the second layer may be the background display. In this case, in the first operation mode, the background display is changed according to the operation of the touch pad 14 without changing the highlighted display position of the selection candidate point, and in the second operation mode, according to the operation of the touch pad 14. The highlighted display position of the selection candidate point is changed.
